The deflection in a galvanometer falls from 50 division to 10 division when a shunt of `15Omega` is used. Calculate the galvanometer resistance.

The Wheatstone bridge circuit have the resistance in the various arms shown as figure Calculate the current through galvanometer

A 25Omega galvanometer is shunted by 2.5Omega wire. What part of total current flows through the galvanometer?

How will you convert galvanometer which needs 50 mA for full scale deflection into a voltmeter reading upto 2.5 volts ? The resistance of the galvanometer is 10 ohms.

A galvanometer gives full scale deflection with 0.2 mA. The resistance of its coil is 1000 ohms. How much shunt resistance is required to converted into an ammeter to measure currents upto a 2 amperers?

A galvanometer having a resistance of 50Ω gives a full scale deflection for a current of 0.05 A. The length in meter of a resistance wire of area of cross section 3×10^−3 cm^2 that can be used to convert the galvanometer into an ammeter which can read a maximum of 5A current is [specific resistance of the wire =5×10^−7 Ωm]

A bullet of mass 10 g is fired from a gun with a velocity of 800ms^-1 .After passing through a mud wall 100cm thick its velocity drops to 100ms^-1 .Calculate the average resistance offered by the wall.

A stone is allowed to fall from the top of a tower 100 m high and at the same time another stone is projected vertically upwards from the ground with a velocity of 25 m/ s. calculate when and where the two stones will meet.

In a potentiometer experiment, it is found that no current passes through the galvanometer, when the terminals of a cell are connected across 50 cm of the potentiometer wire. If the cell is shunted by a resistance of 5 ohm, the balance point is found at 40 cm of the wire from the same end. Find the internal resistance of the cell.
